Site Status

North Penn 7 is divided into four separate areas for purposes of cleanup:

Operable Unit 1 is the soil contamination in four out of five properties that comprise the whole site. One of the potentially responsible parties (PRPs), Ford Motor Company, has completed a soil removal on one of these four properties. EPA has finalized the Screening Level Ecological Risk Assessment (SLERA) of Terrestrial Habitats, and the aquatic habitats Baseline Ecological Risk Assessment (BERA). EPA is in the process of finalizing the Human Health Risk Assessments (HHRAs) for each of the OU1 contaminant source properties.

Operable Unit 2 is the soil contamination on the fifth property, Spra-Fin Inc. Soil cleanup was completed in 2011 on OU2.

Operable Unit 3 is a site-wide groundwater investigation which was completed in July 2011 and the Human Health Risk Assessment (HHRA) was completed in April 2012. In November 2012, EPA's contractor mobilized to the former Teleflex Inc. property at 205 Church Rd, North Wales, PA, for the installation and development of three new groundwater wells for use in the Feasibility Study's (FS's) in-situ bio-remediation treatability pilot. The three new wells, one of which will serve as a substrate injection well, join a comprehensive network of existing wells on the property. The pilot study which will examine the viability of remediating the Site's chlorinated VOC contaminated groundwater plumes through the use of in-situ bio-remediation. The first injection occurred in December 2013. The results of the pilot study will be incorporated and evaluated as a remedial alternative in the Site's groundwater FS.

Operable Unit 4 is a site-wide vapor intrusion study. The first round was completed in April 2011, and the results have been communicated to the property owners. A second round was performed in 2012 and the data is currently being evaluated by EPA. A third round was conducted in early 2013, and a fourth and final round is planned for March 2014. To date, VI has not been found to be occurring at the Site.

Spra-Fin Inc. removed 80 cubic yards of TCE-contaminated soil from an area near a deteriorated tank.

As a result of a lawsuit filed against them by the North Penn Water Authority, all five facilities have agreed to finance the pumping and treating of groundwater to remove volatile organic compounds from public service well L-22.

Contaminants and Risks

Groundwater and soils are contaminated with volatile organic compounds, including TCE and vinyl chloride from former process wastes. People who accidentally ingest or come in direct contact with contaminated groundwater or soil may be at risk.
